How to avoid the impact of high temperature environment on piezoelectric photo machine
High temperature and hot environment is an important test for the use of piezoelectric photo printer inkjet printing equipment. In high temperature environment, it not only affects the normal inkjet printing of the photo machine, but also the electronic card accessories related to the photo machine, inkjet printing operation, and related Print media, image color, etc. will have a certain use effect.
In the environment where the high temperature photo machine is used, it is necessary to pay attention to the space used for the photo machine to cool down. To keep the temperature of the working environment of the photo machine should not exceed 40 degrees, the photo machine will stop working at high temperature and affect the operation. Especially in the long-term uninterrupted printing work of the piezoelectric photo machine, the excessive temperature is likely to cause high temperature of the relevant control board of the photo machine, which affects the printing performance. For example, the high-precision data chip on the main board is likely to cause data when the temperature is high. The impact of transmission, slower printing speed, and even other serious chip and electronic components, circuit damage and so on.
In addition, if the working environment temperature of the photo machine is too high or too low, it will cause the photo machine nozzle to break. Because the ink used in the photo machine has the specified working environment index, the viscosity index of the ink will follow the ambient temperature. Changes and changes, the viscosity of the corresponding corresponding nozzle operating voltage also changes accordingly, otherwise it will cause instability of the nozzle inkjet, easy to break the line, break the ink phenomenon. When the temperature is high, the viscosity of the ink is lowered. At this time, the working voltage of the nozzle should be appropriately reduced. Otherwise, it is easy to form bubbles inside the ink tube, causing no ink to be ejected from the nozzle hole, which causes the white line of the picture to form a photo inkjet printing. Line phenomenon.
Therefore, in the high-temperature photo machine working environment in summer, it is appropriate to use the space for the photo machine to ventilate and cool down. The ventilation of the photo machine workspace is directly related to the temperature of the space. Because of the poor ventilation, the heat generated by the machine and the accumulation of room temperature can easily lead to the overall room temperature being too high, plus indoor and outdoor in summer. The temperature is relatively high. If the indoor space is not well ventilated and the temperature is not dissipated, the machine will be susceptible to temperature and the related fault will occur, affecting the normal inkjet printing of the photo machine. At the same time, the photo machine will be printed when printed. In the non-ventilated working environment, and the high temperature indoor space, the ink will easily produce a strong ink odor, which will give the operator an uncomfortable feeling. It is very necessary to give the photo machine a cool working environment during the hot summer months.
